Cal is packing his suitcase to go on a trip. He wants to pack 4 pairs of pants chosen from the 8 pairs of pants in his closet and 5 shirts chosen from the 9 shirts in his closet. In how many different ways can this be done?
Answers
Answer:
8820 ways
Step-by-step explanation:
Given that :
Selecting 4 pairs of pant from 8 available and selecting 5 shirts from 9 available
Using combination :
4 pants from 8 = 8C4
5 shirts from 9 = 9C5
Recall:
nCr = n! / (n-r)! r!
8C4 * 9C5 = [8! /(8-4)!4!] * [9! /(9-5)!5!]
8C4 * 9C5 = (8! /4!4!) * (9! /4!5!)
8C4 * 9C5 = 70 * 126
8C4 * 9C5 = 8820 ways

x=> -6 is the inequality that represents the answer best.
the smaller of two numbers is 2 less than 1/3 the larger. the sum of the two numberrs is 50 what is the value of the numbers
Answers
The smaller number is 14 and the larger number is 36.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let the smaller number would be x
And the larger number would be y
Given that the smaller of two numbers is 2 less than 1/3 the larger
So x - 2 = (1/3)y ⇒ 3x - 6 = y
The sum of the two numbers is 50
So x + y = 50
Substitute the value of equation 3x - 6 = y in the above equation,
⇒ x + 3x - 6 = 50
⇒ 4x = 50 + 6
⇒ x = 56/4
⇒ x = 14
Substitute the value of equation x = 14 in the equation x + y = 50,
⇒ 14 + y = 50
⇒ y = 36
Hence, the smaller number is 14 and the larger number is 36.

a. f(a) =5a+12
we have 1. a=6
Therefore, where ever we find a we'll substitute in 6
f(6) =5(6) +12
6f=30+12
6f=42
so therefore 1. a=6 will match c on the right
2. a=2
f(2) =5(2) +12
2f = 10+12
2f = 22
therefore 2. a=2 will match a on the right
3. a=4
f(4) =5(4) +12
4f=20+12
4f=32
therefore 3. a=4 will match d on the right
4. a=5
f(5) =5(5) +12
5f=25+12
5f=37
therefore 4. a=5 will match b on the right

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11 A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10 How much does a liter of milk cost, and how much does a loaf of bread cost?
Answers
Answer:
A liter of milk cost $0.75 and a loaf of bread cost $1.75
Step-by-step explanation:
Let the liters of milk by represented by m
Let the loaves of bread by represented by b
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11
3m + 5b = 11...... Equation 1
A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10
4m + 4b = 10.... Equation 2
Combining the Equations
3m + 5b = 11...... Equation 1
4m + 4b = 10.... Equation 2
We solve using the Elimination method
Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m
12m + 20b = 44..... Equation 3
12m + 12b = 30....... Equation 4
Substract Equation 4 from Equation 3
8b = 14
b = 14/8
b = $1.75
Solving for m
3m + 5b = 11...... Equation 1
3m + 5($1.75) = 11
3m + $8.75 = $11
3m = $11 -$ 8.75
3m =$ 2.25
m =$ 2.25/3
m = $0.75
Therefore,
a liter of milk cost $0.75 and a loaf of bread cost $1.75

b) The new ordered pairs are X' (6, 9), Y' (7, 12), Z' (4, 4)
Step-by-step explanation:
If the point (x, y) reflected across the x-axis, then its image is (x, -y), which means to reflect a point across the x-axis, change the sign of its y-coordinateIf the point (x, y) translated h units to the right and k units up, then its image is (x + h, y + k), which means add its x-coordinate by h and add its y-coordinate by k∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)
∵ The points reflected in the x-axis
→ Change the signs of the y-coordinates of the 3 points
∴ X' = (-3, -7), Y' = (-2, -10), and Z' = (-5, -2)
a) The new ordered pairs are X' (-3, -7), Y' (-2, -10), Z' (-5, -2)
∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)
∵ The points translated to be (x + 9, y + 2)
→ That means add the x-coordinates by 9 and y-coordinates by2
∴ X' = (-3 + 9, 7 + 2), Y' = (-2 + 9, 10 + 2), and Z' = (-5 + 9, 2 + 2)
∴ X' = (6, 9), Y' = (7, 12), and Z' = (4, 4)
b) The new ordered pairs are X' (6, 9), Y' (7, 12), Z' (4, 4)

The quotient to describe the rate of change in the squirrel’s height above the ground is 27.619 feet per seconds to the nearest hundredth.
How to find the rate of change in the squirrel’s height above the ground.Given data
height below ground = 45 feet
height above the ground = 100 feet
time of travel = 5.25 seconds
Rate of change calculation
total distance moved by the squirrel = height below ground + height above the ground
= 45 feet + 100 feet
= 145 feet
rate of change = total distance / time of travel

A train leaves at 17.22 and arrives at its destination at 18.14.
If the train travelled 56 km, what was it's average speed in km/h?
Give your answer rounded to 1 dp.
Answers
Answer:
48.5 km/h
Step-by-step explanation:
speed = distance/time
distance =56km
time = 1814h - 1722h
time = 52 min = 52/60h =13/15h
speed = 56*13/15
speed = 48.53
into 1dp= 48.5 km/h
Answer =
So first remember the formula:
Distance/Time= Speed.
Now you see how many minutes it is from 17:22 to 18:14.
17:22 > 18.14 = 52 minutes, 1 Hour = 60 minutes. Hence, 52/60.
Then you get your calculator and do, 56 km/ 52/60
So what I mean is basically 56 km *fraction line* 52 *another fraction line* and then 60 in your calculator. Then you will get a fraction then press SD in your calculator.
You should get 64.6153....
Now the final step is to round it to the 1st decimal place, so
64.6|153 after 64.6 is the first decimal place which is (1) and 1 is below 5 so it will not go up and therefore stay the same so, your Answer is: 64.6 km/h.
Hope it helped!

Answers
Answer:
BCE= 115 ECD=65
Step-by-step explanation:
(5x+10)+(3x+2)=180
8x+12=180
8x=168
x=21
5(21)+10=115
3(21)+2=65
Answer:
<BCE=115°
<ECD=65°
And their sum is 180°
Step-by-step explanation:
< BCE + <ECD =180° ( Being sum of supplementary angle which is formed in the given diagram is 180°)
(5x + 10)° + (3x + 2)°= 180°
5x + 10 + 3x + 2 = 180°
5x + 3x + 10 +2 = 180°
8x + 12= 180°
8x = 180°-12°
8x = 168
x= 168/8
x=21°
Now,
<BCE = 5x+10
= 5*21+10
=105+10
=115
<ECD
= 3x+2
= 3*21+2

Sarah is buying roses and carnations to make center pieces for prom, Roses, x, cos
$3 each and carnations, y, cost $1 each. She can spend no more than $75 on the
Flowers. Which graph represents the solution to the problem?
Answers
Answer: Third option.
Step-by-step explanation:
We have the variables:
x = number of roses that Sarah buys
y = number of carnations that Sarah buys.
Each rose costs $3, then the price for x roses is: x*$3.
Each carnation costs $1, then the price for y carnations is: y*$1.
The total price will be:
$3*x + $1*y
And she can spend no more than $75, then we have the inequality:
$3*x + $1*y ≤ $75
Writing this as a line, we have:
y ≤ 75 - 3*x
Then the graph of this will be:
A solid line with a negative slope and the shaded part will be below that line.
The value of y goes between 0 and 75.
The value x goes between 0 and the value of x such y = 0, this is:
y = 0 ≤ 75 - 3*x
3*x ≤ 75
x ≤ 75/3 = 25
Then the value of x goes between 0 and 25.
The correct option will be the third one.
The correct graph is option 3.
Given,
Sarah buys x no. of roses and y no. of carnations.
The cost of each roses be $3, so cost of x roses be 3 x .
And the cost of each carnations be $1, so cost of y carnations be y.
The total cost will be [tex]3x + y.[/tex]
But as given in question she can spend no more than $75, so we have the inequality [tex]3x + y \leq 75[/tex].
Writing the above equation as a line we have [tex]y\leq 75-3x[/tex].
So graph of above line will be a solid line with a negative slope and the shaded part will be below that line so the value of y goes in between 0 and 75.
Now, value of x when y is o will be calculated from [tex]y\leq 75-3x[/tex].
[tex]0\leq 75-3x[/tex]
[tex]3x\leq 75[/tex]
[tex]x\leq \frac{75}{3}[/tex]
[tex]x\leq 25[/tex]
Now we have values of x in between 0 and 25.
here we have y in between 0 and 75 with a negative slope and x in between 0 and 25. so the shaded part will be below that line goes in between 0 and 75 on y axis . option 3 has shaded part in between 0 and 75 on y axis so the correct option is 3.
